Snowflake recently released their new "geometry" data type. Not to be confused with the existing "geography" data type. The geometry data type can contain geometries in other coordinate systems, not just WGS84. Whereas geography is specifically WGS84.
See Geography vs Geometry data types documentation here
Geospatial Data Types — Snowflake Documentation
When will FME support writing of the new snowflake geometry data types? Is there a way to do this right now, or will it be a future release of the Snowflake Spatial writer?
